Hi everyone, 

my headphones can only be charged, when the charging box is plugged in, as well. Does someone know, what the problem might be?

Hi,

To me sounds like the integrated battery or the charging circuit is defect in the charging box.

So I would recommend to contact an authorized service centre.

Cheers
